' 1 This inventionrelates to truck' or wagon boxes andhas for animportant object there- 'of the provision v of a box which may be' verycheaply and at the same time stronglyc onstructed and whichiscapable ofa' wide range'of use. More specifically itiis the object of thisinvention to produce a wagon box capable of: conversion from a boxstructure toia flat bed or a bed having inclined side walls, the

structure being such that'the flatbed pro vided is of much greater widththan the ordinary fiat bed of the wagon boxand when the inclined sidewalls} are provided, these, are rigidly supported without the use of myinvention, the-parts being shown in the.

Figure 4 is an end elevation showing the device in use as a fiat bed. a

Referring now more particularly to the drawings, a flat bed is providedcomprising longitudinally extending sills upon which of a length greaterthan the width of the wagon boxwhich is to be provided. 'The ends ofthejoists 11 are connected by longi tudinally extending rails 12 seatedupon the these rails a flooring 13 is mounted upon the joists. I thanthe distance between the rails'so that a space 14 is left'between theedges of the 5 the flooring have, formed therethrough aligned openingsl5through which is directed a hinge'bolt 16 which mayconsist of 55oneof'the usual'wagon bolts, as illustrated.

are arranged transversely extending joists 11 upper surfaces of thejoists and'between This flooring is of a width less" flooring and therails at each side of theflooring. The joists adjacent the edges of,

' Box sides 17 are providedyeach consisting of a plurality of-studs 18,to which are secured side boards19"and'20 forming" the s de wall. Thestuds" 18 are of greater lengththan the height of the side wall and havetheir excess length arranged at the lower end of the wall. The hingebolts 16 pass'through these studs a'ndform a 'pivotffor the side.

walls, the point ofpivotal engagement being such thatwhen the sidewallsare vertically jdis posed, the lower edge of the lowermost side wallboard 20'li'es immediately above the adjacent edge of the flooring 13and when the st'uddingand' side walls areinc'lined but avery slightspace is formed between" the f boards 20 and the adjacent edges of thethen 7 ing. fVVhen inan inclined posit iemthe studs have their outerfaces'r'esting upon the sills 12 be Supported thereby andfurther have Itheir beveled lower ends 21 engaged against the side faces of theadjacent sills 10 so that a. two point support resisting the thrust ofload against the inclined side walls is pro vided. to remove strain fromthe hinge bolt 16. j

A selected board, preferably the lowermost board 20 of the sidewall, ismade removable, being secured bybolts 22'and is of thevsame width as thedistance'between the edge-of the flooring and the adjacent edge of thesill 16. The joists 11 are provided with bores 23 for the passage ofbolts 22 so that the sides may be removed by removing the bolt 16,the-boards20 removed and placed'upon the joists to fill the space 14 andbolted in position by the bolts employed for securing.

it to the sides. The rails 12 are preferably V thicker than the materialemployed for flooring and siding so that they project thereabove andwill prevent side shifting of loads arranged upon the fiat body.

End gates 24 are provided, each having secured thereto, ateachsidethereofandade jacenttheir tops, pins 25 projecting atoppo- ;sitesides of the end gate and adapted to en gage in openings 26 formed inthe box" sides 17 when the box sides are moved to vertical 3 position.Each end gate is further provided ing slidably mounted thereina'retaining pin adjacent its lower end with a guide 27 hav- 28 adaptedto engage in an opening '29 Q formed in the wagon bed. As a means forretaining the box "sides in elevated position, bars are provided, as at.30, these bars being of a length to bridge the I distance between theside Walls and having their end port V niodi-fication i thout 1materiallydeparting -=fromthe ,spirit of the invention and Iaccordingly-. ='do: not liinitie inyself to such specific; structureexcept as hereinafter claimed, a
